• The first MR angiographic images were 2D and 3D time-of-flight (TOF) and had a low accuracy because of the tendency to often overestimate the lesion.
• More recently, 3D contrast-enhanced MR angiography increased confidence in MRA and shows a good correlation with conventional DSA for extracranial and intracranial vessels.
• MR imaging also permits the brain parenchyma to be visualized and thus shows the extent of the associated vascular lesions.
• MR diffusion imaging techniques are a unique window to see, very early after stroke, the cytotoxic oedema provoked by an ischaemic injury.
• MRA combined with MR diffusion and MR perfusion imaging has the advantage of giving the clinician a comprehensive analysis of the stroke in evolution and hints at its aetiology.

Diabetes is a disease that affects the way your body uses food. Normally, your body converts sugars, starches and other foods into a form of sugar called glucose. Your body uses glucose for fuel. The cells receive the glucose through the bloodstream. They then use insulin a hormone made by the pancreas to absorb the glucose, convert it into energy, and either use it or store it for later use.
